'Fools' in the Bible

Keep thy foot when thou goest to the house of God, and be more ready to hear, than to give the sacrifice of fools: for they consider not that they do evil.

When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed.

The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth.

It is better to hear the rebuke of the wise, than for a man to hear the song of fools.

Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools.

The words of wise men are heard in quiet more than the cry of him that ruleth among fools.
